The part of the labrum overtopping the clypeus is very wide 

 and the sides of the clypeus are very little prominent so that from 

 the most favourable point of view the " trilobed outline " of the 

 head apj^ears only feebly developed, with the middle lobe nearly 

 as wide as the lateral ones. The clypeal suture is scarcely marked ; 

 the sculpture of the head close and coarse but not deep. The pro- 

 thorax is slightly more than half again as wide as long, its base 

 not quite half again as wide as its front which is moderately con- 

 cave with angles but little produced ; the sides are gently arched ; 

 the hind angles from every point of view appear rounded off; the 

 puncturation is sparing (spaced so that about 15 punctures occupy 

 the length of the middle longitudinal line) and by no means fine, 

 but not deep, and has a slightly rugulose appearance. The elytra 

 are squamosely, lightly and rather sparingly punctulate, their trans- 

 verse wrinkling is conspicuous, their lateral fringe normal, their 

 apical membrane normal. The hind coxae are of the same length 

 as the metasternum ; the ventral series consist of long hairs. 

 The puncturation of the under surface is fairly close and strong 

 on the sides of the metasternum becoming gradually more sparing 

 hind wards, and also becoming more sparing from all the lateral 

 parts towards the middle, but the hind cox£e have not a very well 

 defined impunctate space except at their extreme inner margin. 

 The hind femora are considerably wider than the intermediate, 

 their inner margin being moderately and roundly produced at the 

 apex. The anterior tibiae resemble those of H. Darwi7ii. The 

 produced apex of the basal piece of the hind claws is stout and 

 about half as large as the apical piece.
